Automatic update whilst in the vbscript editing mode

Can someone tell me how to switch off the immediate update/run mode whilst editing the contents of a vb script component in Rhino8. Currently especially when the overall size of the script is large, everytime you do a change (which could be just modifying a letter in variable name) it takes at least a couple of minutes before the system allows you to do anything.

I have had to revert to copying the whole content and then pasting it into notepad to do offline editing.

Many thanks
