I got a reproducable bug, when unintalling Version 1.95
Just done this because I wanted to install Version 1.95.
After uninstalling 1.59 in Vista's system control, all standard programs are gone.
The whole list is just empty.
It seems, that uninstalling deletes all entrys in the following registry key:
HKEY_LOcal_Machine
Software
RegisteredApplications
Fortunally I have ha system backup handy
If tested it two times, each of the uninstall emptys the registered apps.
Cheers
Ralf
