Inno Setup Flag confirmoverwrite not working any more...

[Set me As newtype]

Gents,

I've been using Inno Setup for a long time (now using ver. 5.3.4) and prompting users about overwriting a database file, with perfect success, until recently... Seems the function has stopped working.

I'm sure there must be something I did, but I've been pretty good about documenting my changes and can't find anything...

Here's my script. Please see if you can help:
