Toggled from a Design to Code in the Studio. Everytime that I clicked the mouse to move the cursor to a desired location in the code, the view switched back to "Design". After 3 or 4 tries, I gave up using the mouse and used my arrow keys to the line that I wanted to change, made my change. I wanted to use my mouse to save, but the mouse was not visible when it was on the 2nd monitor where the studio was open... (When I moved the mouse to the first monitor, it was visible but disappeared from view when I moved it to the 2nd monitor. Not being able to see the mouse, I just left clicked it and got the error message below.

After the error, everything worked fine and my changes were there and able to be saved.

Code:
C:\Program Files (x86)\DataFlex 19.1\Bin\Studio.exe
Assert: Mouse Down called with dirty designer view


Error: 4402
