Setting flag to true issue using wm_notify ($DTN_DATETIMECHANGE)

[SupaNewb]

Issue: If either date picker controls receive focus, then use arrow keys to change date in edit portion, flags do not set to True until mouse move or mouse click.

I have used this exact method in the past & it works perfectly. I just can't figure out what I am doing wrong here. The only thing different I can think of is I just updated my Autoit version to ;Autoit v3.3.14.0 & if it matters system I am using is running Win7 Pro x86.

Because changing the date does not generate a control event (but it is the case when clicking on the control)
Move the two lines If $fdpMainChange = True and If $fdpLogChange = True outside the Switch/Case, it should work

Thanks jguinch, Works fine now!
