Regex-based SetFocus Extremely Slow

[armsys]

With the recent versions of MS, I notice a significant delay in SETFOUCS with WIN_REGEX=1.
For example,

Code: Select all

Let>WIN_REGEX=1
Let>Pgm={"^EditPad Pro 7 -"}

Code: Select all

Let>WIN_REGEX=0
Let>Pgm=EditPad Pro 7 -*

The speed of SetFocus resulted from the above 2 approaches is significant different.
Is there a way to speed up regex-based SetFocus?
Thank you.

I don't think this is surprising - it has to perform the regex comparison against all open windows on the system. Clearly there is going to be a performance hit.
