We just started using Sys 7 on our lab IIci's. (8meg memory) PP ST (r4) seems to be just fine, except I have noted one irratating bug. In 32bit addressing mode, PP ST sets some global color variable on the MAC. ST windows default to a sort of grey color. After loading PP ST, ALL Mac application windows come up with in grey color - even after PP ST is quit (this is what makes me think that PP ST is setting some global variable). Turning on VM on the MAC causes no problems that I have seen yet. 32bit addressing mode is clearly the factor. This is not a biggy. But I wondered if others had experienced any difficulties with 32bit addressing mode. ---jon---

I also noticed the bug (?) in the way the windows are cleaned up over the desktop. I prefer to have the default background color of my windows set to veryLightGray but I found that moving them around on top of the desktop leaves little gray rectangles that don't get cleaned up properly (There is no "refresh windows" command on the Mac desktop!). However, there seems to be no problem with the default for window backgrounds set back to white, so if that's what yours is set to I don't know what the problem could be. One annoying consequence of running under System 7 is on placing windows on opening. I set my window default to allow the user to place and resize the window when they first open (like v 2.5 used to do), but under System 7 you have to be careful not to place the first mouse click point over the desktop. The operating system interprets that as a context switch and the desktop will become active (along with a marquee)! Another trick I learned today was that in R4 you have to grow memory in order to make use of it. My Mac IIfx has 20 megs of RAM so under System 7 I can finally make full use of it. I allocated 20 megs to the Objectworks application but when I would garbage collect it only reported 1 meg free! After consulting the kind folks at ParcPlace I learned how to grow my memory.
