All right, okay: you're stuck. You're trying to use one of the
tools on an image, and nothing is happening, and nothing you try
makes any difference. Your fists are starting to clench, and your
face is starting to feel warm. Are you going to have to kill the
program, and lose all your work? This sucks!
</p>
<p>
Well, hold on a second. This happens pretty frequently, even to
people who've used the GIMP for a long time, but generally the
cause is not so hard to figure out (and fix) if you know what to
look at. Lets be calm, and go through a checklist that will
probably get you GIMPing happily again.

<span class="bold"><b>How to tell:</b></span> If there is a
floating selection, many actions are impossible until it is
anchored. To check, look at the Layers dialog (making sure
it's set to the image you're working on) and see whether the
top layer is called "Floating Selection".
</p>
<p>
<span class="bold"><b>How to solve:</b></span> Either anchor
the floating selection, or convert it into an ordinary
(non-floating) layer. If you need help on how to do this,
see Floating Selections.

<p>
<span class="bold"><b>How to tell:</b></span> If this is
the problem, merely reading this will already have made
you realize it, probably, but to explain in any case:
sometimes the flickering line that outlines the selection
is annoying because it makes it hard to see important
details of the image, so Gimp gives you the option of
hiding the selection, by unchecking <span class="guimenuitem">Show
Selection</span> in the
<span class="guimenu">View</span> menu. It is easy to forget that
you have done this, though.
</p>
<p>
<span class="bold"><b>How to fix:</b></span> If this
hasn't rung any bells, it isn't the problem, andif it has,
you probably know how to fix it, because it doesn't happen
unless you explicitly tell it to; but anyway: just go to
the <span class="guimenu">View</span> menu for the image and, if
<span class="guimenuitem">Show Selection</span> is
unchecked, click on it..

</p>
</div>
</div>
</div>
<p>
<span class="bold"><b>How to fix:</b></span> If doing this
has destroyed a selection that you wanted to keep, hit
Ctrl-Z (undo) a couple of times to restore it, and then
we'll figure out what the problem is. There are a couple
of possibilities. If you couldn't see any selection,
there may have been a very tiny one, or even one that
contained no pixels. If this was the case, it surely is
not a selection that you wanted to keep, so why have you
gotten this far in the first place? If you can see a
selection but thought you were inside it, it might be
inverted from what you think. The easiest way to tell is
to hit the Quick Mask button: the selected area will be
clear and the unselected area will be masked. If this was
the problem, then you can solve it by toggling Quick Mask
off and choosing Invert in the <span class="guimenu">Select</span>
menu.

<span class="bold"><b>How to tell:</b></span> The Layers
dialog gives you ability to toggle the visibility of each
layer on or off. Look at the Layers dialog, and see
whether the layer you are trying to act on is active
(i.e., darkened) and has an eye symbol to the left of it.
If not, this is your problem.
</p>
<p>
<span class="bold"><b>How to fix:</b></span> If your
intended target layer is not active, click on it in the
Layers dialog to activate it. (If none of the layers
there is active, the active drawable might be a channel --
you can look at the Channels tab in the Layers dialog to
see. This does not change the solution, though.) If the
eye symbol does not appear, click in the Layers dialog at
the left edge to toggle it: this should make the layer
visible. See the Help section for the <a href="ch04s02.html" title="2. Layers dialog">Layers Dialog</a> if you

<span class="bold"><b>How to tell:</b></span> In Gimp,
layers don't need to have the same dimensions as the
image: they can be larger or smaller. If you try to paint
outside the borders of a layer, nothing happens. To see
if this is happening, look for a black-and-yellow dashed
rectangle that does not enclose the area you're trying to
draw at.
</p>
<p>
<span class="bold"><b>How to fix:</b></span> You need to
enlarge the layer. There are two commands at the bottom
of the Layer menu that will let you do this: Layer to
Image Size, which sets the layer bounds to match the image
borders; and Layer Boundary Size, which brings up a dialog
that allows you to set the layer dimensions to whatever
you please.
