I have a customer using 7.2c. They've recently upgraded. As they live in the communications area of CRM the notifications were of particular use to them. It would be common for users to have upwards of 5 or 6 on the screen at once. In prior versions to 7.2 this would have made most of the screen appear to be notifications and they would be scrolling up and down all the time. Since upgrading and with the frameset removal and the new notification area, you'd think they would have been happier. This is surprisingly not the case.
Firstly the notification area isn't immediately attention grabbing so they forget to look there. I altered the style sheets so the notification number showed up in a red box rather than the standard theme colour which made things at least immediately visible. However, some users have said that the notification area sometimes doesn't show the correct number of notifications. They could have 5 or 6 in there but it might only say 1. When they expand it seems to then update properly.
Has anyone come across this before? I logged it with support but they've not had any mention of this. I can't replicate it simply because I can't create loads of notifications for lots of different users to fire at different times. It just does't work when testing.
