Coherence problems with PD 3 & 10.4.10
Well I had problems going into coherence mode after the 10.4.10 install (would receive a "out of video memory, unable to set guest OS screen resolution" error). Full-screen and os-window modes both continued to work fine.
Tried increasing video memory to 24 Mb (per the error msg), no help.
Re-installed parallels tools, that fixed the problem. Reduced video memory back to the original 16 Mb, coherence still worked fine, so all was good.
Btw my config is mbpro, core2 (1st one), 3 gb ram, parallels 3 build 4128, windows xp pro sp2. PD is set to consume 1 gb, auto-preallocate virtual memory.
