Hi fellow VB-Coders

I am developing quite an amazing text-editor (if I shall tell my own opinion). There's just some little problems with it. I have a suspecion, that my app uses way too many of the system resources, which makes it unstable and gives me a lot of errors like "Out of Stack space" and so on, which again causes my implemented Error Handler to go crazy and the whole thing terminates with the sweet little "Illegal Action" error thing as a result of it.

I'm using a 700MHz computer (Athlon processor) with 128 megs of PC133 RAM, so something is way wrong, if my app uses up all that memory just by using it for half an hour or something.

I would be very grateful if someone can give me some ideas of what could be wrong, and maybe give me some general things to do, to get the best performance of an app.
