I REMed that, and now loading Firefox DLLs high doesn't seem to crash at close (at least not as often, I have only done it half a dozen times).
Well, it is a little better, but still not useable. It would be good, if it wouldn't crash when I close it. When it does crash, it seems to mess up my profile. I cannot run FF, loaded low, at all, without DLLBASING=OFF. T'Bird is even worse, but that is probably why Above512, and Free Shared Mem don't show the memory being returned to the pool. FF, and TB, may not be able to load XUL.DLL because there is no contiguous area of memory to put it in. Unfortunately, I seem to have run out of things to remove, to free up more shared memory.
Don't use any of Doodles Cairo screensavers. Really they need to be updated to use current Cairo as the early versions of Cairo were buggy.
First I have heard of that. I did have one problem with DSS, where it would go to the screen saver, and it was impossible to wake it up again (the system was running fine, in the background). That happened when I happened to move the mouse, or press a key, just as it would start saving. I turned DSS off because of that. In this case, it doesn't seem to make any difference if it is turned off, or not. Just having the Cairo clock selected seems to eat up some shared memory space (not a lot, but some). I am going to leave DSS enabled, with the blank screen saver, and see if that happens again. If it does, I will probably uninstall DSS, since it really doesn't do anything useful anyway.
