This question already has an answer here:
I had two screens connected, but now I disconnected one and took it away (it is not available any more). The problem is that I have DVB Viewer installed (DVBViewerTE from Technisat) and the last position of that window was in the other screen. Now I cannot move the window to the first screen - I cannot watch TV, I have only sound.
I tried everything, but the DVBViewerTE is some sort of freaked pre-XP custom made toolkit. No shortcuts work. No Alt-Space, no Win+keys, no Ctrl+Win+Keys, no Shift+Crtl+Win+Keys. Registry don't contain any "last window location" settings, nor the Program files folder has any config file with these.
The only solution is to reinstall, but I would like to know if it is indeed everything I could try.
