system error code 1400 invalid window descriptor

[hopalongrock]

(translated from Hungarian).
Very rarely do I get this error, and only now realized the reason:
somehow the explorer stopped and restarted (Either by me or a program).

After pressing OK, It seems that TGF is working further, but I rather stop and restart it, without any problem.
Using XP SP3.

(I do not have this problem with other programs)

You mean windows explorer?

[hopalongrock]

Yes.

For example, yesterday I tried a junkware removal program, probably it stopped and restarted the windows explorer, but I don't know/remember exactly.

This probably happens only on XP since I can't reproduce and It might prove cumbersome to find and fix if it is even possible

Thanks, it's a rare and caused no harm.
(Otherwise it's "Invalid window handle" as I found with Google.)

The error message occurred after both an installation of version .80 over a long used (and wonderful) installation of version .72 and it occurs after an uninstallation of the previous version and a clean installation.
