When running multi statement scripts with F5 Execute as Script the results get outputted into the Script tab. Along with script output are script grid tabs. If I run a lot of statements a grid tab will be created for each of the statements and depending on the size of my output pane the grid tabs will fill up the pane. At this point it will crash Toad.
