Wow! Nice works team CP! Your screensaver is really nice.

On my laptop, the screensaver freezes (around of 50%) when the video revert back to desktop and/or to blank screen. It runs fine otherwise.

Toshiba Satelite 2400 with the latest BIOS (v1.40)
S3 SuperSavage/IXC1179 video card
Windows Longhorn 4074

Problem is (possibly) not with OpenGL drivers intalled on my OS because I also get another OpenGL screensavers who runs fine on my system.

The only way to restore the display is to toggle between LCD, CRT and TVOUT modes (Fn-F5).

Hi, when you run the graphics "regular" (not screensaver), i.e. in the GUI right-click on a workunit and "Show Graphics", does it display OK? If that's fine going back and forth (i.e. opening & closing the smaller graphics window) perhaps it's a problem with the BOINC screensaver "engine." Did you copy the new boinc.scr from our 4.02 distribution to your windows/system32? I wonder if it's using an older BOINC installation (assuming you were using 3.x etc) that was in windows/system32?

Run perfectly. Can minimize/maximize/resize window without any problem. Of coarse, I cannot test it in full screen video mode.

I think the problem must with the BOINC.scr engine not with the CP software. The bug should occurs when the OpenGL driver release display control to Windows. Boinc.scr is a full screen OpenGL application and regular graphics must be a windowed OpenGL application (not sure for the latest).

I tried both, same results.

I found something. May be useful for debugging. If I disable all DirectDraw and Direct3D accelerations, as well as all cursor and advanced drawing accelerations, all is working fine. Naturally, refreshing rate is very slow without these hardware accelerations.
