Hi I've been very impressed with Parallels Desktop to date encountering very few issues, whilst I've been using it on my macbook pro since the commercial beta. I find my self needing to down grade from build 3170 release candidate to 1970 as I think, based on previsous posts this is the only way to get screen resolutions > 800x 600 with Suse Linux 10.0. I need this version of Suse for other reasons and cannot use 10.1 which works fine with 3120 and 3170. I am assuming the only clean way of doing this is to uninstall 3170 and reinstall 1970 can anyone confirm this? I'd also like to know if 2 versions of paralells can be run on the same host machine? Further are VMs created with one version backwards compatible with previous versions? TIA. ReadyEddy
