CPU usage jumps to 100% when saving if edit window minimized

[frantik]

This is a strange bug that I've had ever since installing PTMP 8.0. It has persisted thru each CS update and continues with 8.0.1

This will happen even with a newly created blank session. If the edit window is minimized, and I attempt to save a session, the CPU usage will jump to near 100% (as displayed using Windows Process Explorer - the PT System Usage window does not display any overloads). The keyboard does not respond to commands in PT, and most menus are greyed out, besides File, Window and Help. In the File menu, only Exit is not disabled.

If I restore the Edit window by clicking on the restore window button on the window's title bar, the CPU load immediately drops back to normal, and normal function of the program resumes. If I close the edit window without restoring it, PT will have to be closed via the task manager. If I display a menu or click on a window title, the CPU usage will drop to normal, but will return to maxed out as soon as I release the widget.

This problem occurs when saving both to the local system drive and an external firewire drive.

I just installed quicktime and trashed my prefs.. no changes.

It's not a huge huge deal, i've learned to not minimize the edit window, but this bug really seems like it ought to be sorted out. I can't believe i'm the only one who has had this problem.

WinXP SP3, IE7 (occurred with IE6 as well). only RTAS plug ins i have are the included ones from digi design and some demo Massey plug ins. I also have the fxexpansion VST wrapper and a few free vsts wrapped.. but like i said, this occurs on a totally blank, newly created session.
