Forums -> UltraMon™ -> Firefox 2.0 nspr4.dll error when moving to new screen
John Lewis   2006-12-07 00:48
I'm getting the following error when clicking on the button to move firefox 2.0 from one screen to another:

UltraMon: UltraMon.exe - Unable To Locate Component This application has failed to start because nspr4.dll was not found. Re-installing the application may fix this problem

This happens on both XP and Vista

The current version i'm running is:
Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.8.1) Gecko/20061010 Firefox/2.0

Any ideas?

Unfortunately I don't know what might cause this.

What's odd is that it looks like UltraMon.exe gets started, but clicking an UltraMon button will never start a new instance of UltraMon.exe (UltraMon.exe is already running).

I also can't reproduce this issue, I tested on XP Pro SP2 with UltraMon 2.7.1 and the same version of Firefox.

I am getting the same error when moving Firefox 2.0 between windows. This happened to me on both Vista Business and XPSP2.

Actually, my error message is different:
I get the following dialog box:
Ultramon: Ultramon.exe - Unable To Locate Component
This application has failed to start because nspr4.dll was not found. re-installing the application may fix the problem.

I have to click OK twice, but then the window switches screens as expected.

I'm having the exact same issue, only with Firefox 2.0; all other applications move between monitors without the annoying popup.

Another user has found a fix for this, see this thread for details.
