Problem with 'Select and Run' in PB 10.5

I have a problem using the 'Select and Run' menu item in the main menu of PowerBuilder 10.5.

I inadvertently clicked on 'Select and Run' in place of selecting 'Run' the other day.

I find that although I now try to use Run, it always prompts for the 'Select data source' (i.e. the normal response of the 'Select and Run' tab.

How can I reset the environment to avoid this hugely annoying prompt - i.e. having to always respond to the Select data source' request every time.

I cannot find a system setting that allows me to recover from this problem.

I have tried uninstalling and re-installing the tool, bit to no avail.

Any help will be really appreciated!
