Error message "Error expanding Content : Missing % after :!"

Hi,
unfortunately I get an error: “expanding Content : Missing % after :!” when using variables with a leading hash-sign in it.

Following situation:
1) Create Variable: #MyVar#
2) Set Variable to “Test”
3) Use variable in “Save Variable to ini action” or inside a “Write to text file” - action using %#MyVar#% to expand the variable.

Unfortunately this does not work, but I need to use those vars with leading and trailing # (for a 3rd Party program that use them).

I am currently working with FB Pro 6.3.0.2253, but also tried latest FB 7 (Trial) with no success…

Is there any fix/workaround for this?

Thanks much & Regards,
Martin

PS: I added a very simple/simplified demo project reflecting the above case…

#name# is an alternate (deprecated) syntax for Action List Parameters, so you need to escape them : ##name##
