After selecting PANTONE the cursor stays a circle for a while.  We cleaned out the items in the temp directory.  The first time we did this after we cleaned it out it seemed to work fine, the second time it was lagging again.  We shut down product and launched and the same thing.
customer sent the last 3 journals they are attached to this case, this didn’t provide any clues. logging in as a different person made the problem go away. Logging back in as yourself the issue returns.
