Has anyone else found DP4 to have extremely annoying Finder freezing? Also, one bug I've noticed, the contents of a folder frequently will appear empty or unchanged until you manually refresh it (by hitting back then forward or reopening the folder somehow). Sometimes it takes several tries. My number one hope is that this extremely annoying bug is sorted for DP5.
I've actually noticed that on occasion although it was infrequently enough that I didn't think much of it and never filed a bug report. Is it happening all the time for you? Can you reproduce it on demand?
If I were you I'd file a BR. I'll have to keep an eye out for this issue myself, will see if I can spot a pattern.
