QuickBooks fatal error M=1188, L=3476, C=315, V=0 (0x0)

Here's one that so far no one else ever found the solution. This may be just one solution but after looking all over the internet, seems to be the only one.
To solve this you need to notice on the panel on the left labeled "Open Windows". You will find quite a few windows open and when you try to do most anything you get the error. The number of open windows is stored in the data file so every time you open it you set yourself up for the error.
The solution: Just close the darn windows until the list is bare and then save the data file back. Presto! No more errors!
