Whenever i minimize Soldat (generally with Alt-Tab) the window 'vanishes' and cannot
be restored (Does NOT appear in the task manager as an application, but it DOES appear under Processes)
I haven't really tried the windows key or F9, but this has never happened to me on previous Soldat versions.
My system specs are: 80 Gig harddrive, 1 Gig of Ram, Intel Pentium 4 Processor - 3 Gigahertz, Windows XP SP2, and NVIDIA Geforce 7300 LE.
