Unable to see Outlook/Calendar reminder pop-ups

I am having a weird problem that I haven't been able to find anywhere on the net. I am using Windows 7 / Outlook 2007. I have Calendar set to pop-up appointment reminders. I get the reminder sound, and when I mouse over the icon on the task bar, I see that two windows exist, one Outlook, one Reminder pop-up, but I cannot get the reminder window to open up or take precedence. Whenever I click on that window, it either just goes to Outlook or to the desktop, depending on what is taking precedence at the time. Any help would be greatly appreciated. This one has me stumped.

There might be some problem with the installed Microsoft office in your computer and that is the reason that you are getting the problem. If you want to solve this problem then you can install the ms office once again and see if that can solve the issue for you. The best way to do that is to download the new setup and install from that. I hope that this will solve the problem for you.
