I also experienced the problem with the error loading : no DPMI memory, while I was experimenting with Windows...When I run Executor under windows, I have 8 meg RAM, and 20 meg virtual memory...IExecutor ran quite slowly, with heqavy disk access...However, I thought I'd turn off v memory, and the n it just wouldn't load up period...I don't seem to remember the heavy disk access with Executor before, but who knows... later -ocean
