This works fine for me, but I only run Windows 7 in a VM, and probably don't have special aero effects enabled, which could make a difference.

Maybe you could try turning off aero, or playing with the taskbar preferences, and see if you can get it to work?  Then we'd know exactly how to reproduce the bug and maybe somebody who has an actual Windows 7 installation could test and fix it. :-)

I use Tomboy on Windows 7 RC (still!) with Aero effects enabled on a physical machine and didn't noticed this problem either. Does this happen every time? Have you tried to enable logging for a Tomboy session and see it there are errors logged?

Start Tomboy from the command line with the --debug option.
.\Tomboy.exe --debug

The log file is saved in %LOCALAPPDATA%\Tomboy\tomboy.log

Here is my log:

I am having the same issue. When I click on "Search All Notes" option the "Search All Notes" window appears in the task bar but will not open in a regular way.  The only way I have found to open it is to right click on it and then select maximize.  This happens about 95% of the time.  The other 5% of the time it works as expected.  I am using version 1.1.1 on Windows XP SP3.  

Previous versions of Tomboy have worked as expected.

This is probably the same as bug #606110, fwiw.  Except Search window coordinates are stored in prefs.xml.  Anyway, the fix will probably be the same.

I should also note that after the window is maximized using the method I described above the window has only two states.  Maximized and minimized.  It is not possible to resize or move the window.

Yeah, this is because it has offscreen coordinates.  You can probably change the x/y coordinates in prefs.xml to 0,0 while Tomboy is not running to fix it, although if this keeps happening there's probably a reason for it (multiple monitors maybe).

Ethan: Is this still an issue? Did you fix this?

A quick workaround for "offscreen" windows:

1) Activate the window (left click on the task icon)
2) Hit Alt + Space (this opens the system menu from the upper left corner, which you cannot see right now, of course)
3) Hit m (for "_Move")
4) Hit any arrow key (up/down/left/right, whatever)

The window is now in "movement" and will float to your mouse position. Move the mouse and the window will appear right under it. Click to release it.

Still, would be nice to understand how this happens: Do you have more than one monitor? In which constellation (Laptop w/ external monitor? Desktop with 2+ monitors? How are they arranged? Which one is the primary desktop with the taskbar?
