Yes, all : refocus, unsharp mask, noise reduction etc... and also all plugins witch use imageguidedlg dialog implementation (free rotation for example)

The both dialogs use the threaded image filter class.

I'm sure, i can reproduce the problem here, on my wife's computer : PIV-3.2 Ghz, 500Mb with hyperthreading.

I have seen that more cpu is speed, more the problem is reproductible. For example, at work, i have another PIV HT computer where i have decreased the cpu speed, and in this case, the crash is more difficult to reproduce. Of course, if i disable HT, the crash do not appear.

I have tested under Mandriva 2005-2006 and Suse 10.1. 

The crash sound like an disynchronism, or something like that. 

Marcel, are you seen in amarok : there is a method to controling HT :

... look void App::fixHyperThreading() method...
