That is hugely better!! Not perfect, but such an improvement that I don't think it'll cause a problem. I also tried complying with the beta version and that also helped a bit. Thanks for your help. P.

I've tried ShellExecute with a blank VBScript and notepad with the same result. I thought ShellExecute was the only way to launch an application with a parameter. I'm new to this, what are the other methods?

I've written a very simple program that detects when a user locks/unlocks their PC and fires off a VBScript (with a parameter) via the ShellExecute method. It works very well except I've noticed that every time I fire the ShellExecute command I loose memory. The first time about 3Mb and then about 50k thereafter. I've recompiled the program without using ShellExecute (not much use but it proved a point) and memory usage was solid. Wouldn't be a problem but some of our customers won't restart or logoff their PCs for weeks at a time. Before anybody suggests it, I can't put the code in the VBScript in to the complied application for "political" reason Many thanks, Pete
