[oXygen-user] very slow response when switching back to oXygen

Hi all, I'm a pretty new oXygen user (new since version 9.1). Really love the tool! But one thing that is really annoying is that if I leave oXygen for awhile (say, 20 minutes), and then come back to it, it usually takes at least 20-30 seconds before it starts responding, and it can sometimes take several minutes. I guess it's some kind of memory paging issue or something. This sometimes happens with other programs too, but it's much worse with oXygen than with any other program that I use. Is there something I can do to configure oXygen to get rid of this problem? I'm running oXygen 9.2 on Windows XP. Thanks, Seraphim
