Duane,

   This seems to be an older post with no replies, however I'm having the same problem with DNN 4.3.7 and Events 3.3.7. Did you ever get this problem resolved? I originally thought it was associated with recurring events, but I'm not sure thats completely true at this point...   Thanks, Peter

I think I actually fixed this problem yesterday after drilling down a bit (just picked up a WROX book on CSS last weekend, Richard York). What I found to be an anomaly in my mind was the use of the overflow parameter in desktopmodules/events/themes/fixedblue/fixedblue.css at location .eventdayscroll . Here the parameter was set to auto. I changed this to scroll and it fixed the behavior but set all the day containers to have scroll bars to the right and at the bottom. This wasn't acceptable for my calendar view, however in looking at this set of parameters I found the height value set to 85% for some reason. I changed the height value to 100%, recycled my site in IIS, and refreshed my browser and the flashing scroll bar behavior was resolved. It seems to continue to work well at  this point. I'm not sure if this is technically the best solution to the problem, but its what I'm going to run with for now... Peter
