It happened on my old rig - only 2GB of Ram, core2 5650
Now I'm working on my new laptop - slightly better config, i.e. 4GB, core2duo 6600
Every time I start PVD I better resist the temptation to use it for at least 5 seconds until it decides I'm allowed to use it, otherwise it freezes, which is sooooo frustrating.
To make editing/saving faster I followed your advice and deleted twitter plugin - works!
Am I the only one suffering from it? Is it cause my DB is currently over 2500 titles?
I cannot do anything else but cling to the lingering hope for this issue eliminated in v 1.0
peace
