The hand or pointer cursor gets selected and the user cannot select any other tool. It is a very weird problem with Fireworks versions (Macromedia 8, Adobe CS2, CS3, CS4 and CS5).
It has happened in my laptop running Windows XP Professional SP3 first with Fireworks CS3, then opened Fireworks 8 and still the same, also happened in a Mac OSX with Fireworks CS5. Other people have also experienced this issue, here you can find an open thread in Adobe forums talking about this same error and another one in Layers Magazine, similar but with Adobe Illustrator CS2.
The solution is to select the tool and press the Spacebar key (thanks Angela). If that doesn’t work, minimize and maximize the window or try pressing Alt key and clicking on a tool, then with Shift key and press some tools, then minimize and maximize again. You can also try restarting the computer or the application but you should not delete your preferences since it seems not to work.
If the suggested solutions don’t work and you still get the bug, try selecting the Text tool (T shortcut key) and create a text box. Thanks Olaf for this solution :-)
Vista users: Another solution if the hand keeps coming up is to try to minimize Fireworks and then go to another application such as Firefox. Thanks John!
Vista users: Go to File > Preview in Browser > Preview in firefox.exe. Thanks Mike!
