First of all, thanks to Sun (and the former InnoTek fellows) for this wonderful program! Since I tried VirtualBox for the first time, all the bugs or glitches I encountered are squashed, however one problem remained. I'll try to explain it as clear as possible (excuse me for my English).
VirtualBox installed on a Windows XP SP3 computer, witch the very same OS as a guest (with guest additions installed). When I put my computer in standby, and I move my mouse or tap the keyboard to wake up it, the screen remains black or the computer reboots, this depends.
Things I've tried in VBox:
I've made an installation using the IO-ACPI option, and also tried it with a guest without the quest additions installed. Also the usage of IDE or SATA virtual hard disks made no difference. Also enabling or disabling VT-x didn't change the situation. (The first version of VirtualBox I've ever tried was 1.5.2 and was causing the same problem back then.)
Other things I've tried:
My former visualization program "VirtualPC" caused no standby problems. Also a trial version of "VMware" caused no problems.
I have a Intel DP965LT motherboard with the latest bios, and a Intel Core2Duo E6300 CPU, this might help.
Hope somebody can help me since I would really like to dump VirtualPC for VirtualBox
