I get this same problem. It works from the 0,0 point as reported, and also works to drag-resize the screen using the bottom right corner, but not if you resize using the keyboard. In the case where it doesn't work the document window stays in the same place and size, and the containing window maximises, the screen looks jumbled.
I'm using WindowMaker 0.91.0, this problem occured on my previous open office installation and also on the current version 2.0. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
