xpcom.dll not found?

Often when I use stroke-it in Firefox I get an error that pops up with the following message:

StrokeIt: strokeit.exe - Unable to Locate C...

This application has failed to start because xpcom.dll was not found. Re-installing the application may fix this problem.

Any ideas about what could be causing this? The error only occurs when I use stroke-it to do the commands and not when I do the actual keystrokes (or press buttons to minimize, etc.)

I get a similar problem only it is "The procedure entry point NS_ Alloc could not be located in the dynamic link library xpcom.dll"; this only happens when using stroke-it to min/max/restore firefox. Have not found a solution yet. Using win XP tablet edition (SP2) .

The xpcom.dll from the OpenOffice suite works; it removes the error I had, and seemed to work fine except it broke the GeckoTIP extension I need to make firefox work well with my tablet PC. If you don't have a Tablet PC using the OpenOffice xpcom.dll might work.

Partial solution to my problem: Send keystrokes. Instead of using the strokeit minimize command use the "Keys- Send Keystrokes" command and send the appropriate keys ie to maximize:

[ALT_DOWN][SPACE_DOWN][SPACE_UP][ALT_UP]x

Unfortunately this won't restore the window to it's previous state if it is already maximized as the Stroke-it maximize command does.

To fix this problem try copying the XPCOM.DLL from your firefox install directory into the windows system directory.

to fix this problem with XP tabletPC edition 2005, copy the three files from
"C:\Program Files\Mozilla Firefox" to "C:\WINDOWS\system32"

xpcom.dll
nspr4.dll
xpcom_core.dll
plc4.dll
plds4.dll
