This might be the same thing my team is seeing, and it happens very intermittently. In any text field they type in, it starts not typing certain characters. It's almost like there is a delay because if you see it happening and you start typing really slowly, (like pausing a few seconds between each key), then it types ok. I seem to be the only one that hasn't experienced it, and can't figure out why.
To answer Jon and Paul's questions: We are not using a localized version of the application, we only use IE so I can't have my team use another browser, there is no specific characters that it is happening with, yes we have form modifications, and we're running a fresh install of SDM version 14.1, c2, with an upgraded 12.7 version database . nd they only started seeing this happening after we upgraded to 14.1.
I've not submitted a support ticket for it since it is so unpredictable, but it seems that it only lasts a minute or 2 and clears on it's own, or if you log off the application and log back on, the trouble clears.
