Executing the script using the shortcut key assign will launch the ExtendScipt Toolkit in some machine.
Problem may not be the Script because it works normally if double-clicking is used to execute instead.
What shortcuts are you trying to use? If they include the Shift or Alt/Option keys, then ESTK is being fired up because that's what those keys do if you hold either down when launching a script.
Used SHIFT+numbers for my shortcuts.
Is there any way to disable that? I mean disable use of the Shift/Alt/Option keys to launch ESTK?
Because we don't really have much choice for shortcuts as many has been reserved in INDESIGN by default.
