I am thinking your Photoshop Preferences are corrupt. Try resetting them. Failing that, a reinstall might be in order.
Hold down Ctrl-Alt-Shift while starting Photoshop. You should get the reset dialog.
nope doesnt help unfortunatelly!
To where are you saving? Is it your local hard drive? Over a network? To flash drive?
Also, how big is the drive and how much free space is available?
If you are on a Windows system, has the drive been defragmented lately?
IF Mac, have you run Repair Permissions or Verify lately?
Any system specs you can give us might help.
Mainly to a NAS Raid over Gigabit...but worked fine for over 2 months now...suddenly it stopped.
over 4TB free without being recently defragmented or being fragmented heavily...
If i export to the Local SSD it works fine as it seems....but isnt there a solution for this NAS issue?
Really a pain for roundtriping to Lightroom....
