Fastkeys Text Expander not working

As per the subject, I use Fastkeys text expansion considerably, including for email signatures. Similar to AutoHotKey (AHK)

I have a number of simple shortcodes, usually beginning with a ‘.’ to activate the text completion - eg .si1 generates a multi-line text output signature.

I can’t get this working in eM Client! It just works in every other windows program I use.

It does also have and takes control of various keyboard shortcuts - although I don’t really use them. Perhaps eM Client is disabling it because of those??

Any thoughts / suggestions?

Thanks
Klaus

It’s actually just started working with no further input or changes! Prior to this I had tried running as administrator and other suggested fixes.
