We are currently using CPS 12.0.10.2061 in a Citrix environment. We have identified why this happens and have temporarily solved this issue, with a workflow process, in our practice.
The Cause:
When making changes in a note, opened full screen, if a change that is made in the note updates anything in the chart summary, open full screen behind the note, you will get a shrinkage due to loss of focus on the note. The note change changes the chart summary and creates the focus on the chart summary instead of the note shrinking it.
The Solution(until patched properly):
After opening a note minimize the note and minimize all windows, including Citrix window and JBoss, to the taskbar. Maximize your note and the shrinkage should not return for the duration of your update.
SP 11 was suppose to fix this issue... we are still having the problem at our site. Anyone else in the same boat?
