as a quick follow-up, if I manually edit the designer.vb file and add the features, they stay....therefore it is an issue with the designer integration....
ANd also, if i had changed them manually, then open the form again, and edit in the properties window....ALL of the customizations I made in the designer.vb code disappear and I have to start again.....argh
I am using:
- Vista Ultimate 64bit
- Visual Studio 2008 Professional
- Quadcore E6600 machine with 4GB RAM
