and recently noticed additional crashing behavior on Windows 7 (64Bit) without any apparent reasons. Based on one of our previous posts, after dwelling into possible reasons figured out the following!

Few of the database level procedures were modified with more parameters(IN and OUT) which was causing the developer suite to crash down.

So, prior you make changes to database level procedures or functions, MAKE SURE YOU DO CHANGE THE PROCEDURE/FUNCTION CALLS FROM YOUR FORM MODULES with all new IN and OUT parameters, then proceed with compiling your Procedures and Functions @ database level. If anybody is aware of another method to deal with this situation, please pass the information through comments.
