Hi,
I never had any problem with PM. Tonight, as I updated to PM5 built 15451, PM became very slow and behave strangely.
a) it opens very rapidly about the first 50 photos (to fill my 30" display) but I have to wait minutes for the other grey slides to show images
b) it stops working once in a while, randomly
c) when it goes crazy, a light grey background appears everywhere, the window moves up half the menu bar, outside of the display, I can't click anywhere, etc.
I did the update as usual, never got any problem before.
I run Windows 7 64bits OS, 16Gb RAM, and data are on external HDD.
What could be happening?
