Okay - Reloading did not sort out the problem.

I noticed that on opening the project it worked correctely but as soon as I add a new form the intellisence would not load up properly but flash.

The project is very big with a lot of usercontrols and activeX exe modules. I compiled some of the objects and removed them from the project and then the intellisence started working correctly.

I assume the problem was a memory problem and the IDE could not load up the intellisence data so it would close down shortly after starting up.

- Any better conclusions ???
