Jesus, DDE is NOT fun!

I am going to eat my furniture in a moment! I have a Lenovo R500, 3 GB memory and my HDD still has 40 GB of free space. I am running Vista64 and Lotus Notes 8.5.2. Working with Domino Designer for Eclipse is a nightmare on my system. It takes 2 minutes to start, it takes another 2 minutes to start Java Tooling etc.

Once started the DDE hangs every now and then, e.g. when saving design elements or when trying to open a design element. I can’t say why that is. Someone told me he reckons that DDE interferes with a Domino Server running on the same machine, but I have no Server installed whatsoever.

I set up a VM with WinXp32 as OS and installed Lotus Notes 8.5.2 on it. I granted my VM 1 GB of memory. Guess what: DDE runs heaps better than on my local machine. Startup time is much faster, no hangs or crashes. Can anybody tell me why that is? Is anyone experiencing similar problems? Is Vista64 the reason?

Arrrgghhh! Give me back my Lotus Notes Designer performance!
