STOP-sign does not appear.

Hi,

I have an form with a subform. I read with a scanner barcodes which you see in de subform.
After 15 seconds inactivity a ticketprinter prints the report of the products and description. This takes about 2 seconds. The coordinator may not scan products for 2 seconds. I can't set off the scanner because it is a dropbox. Behind the subform there's a STOP-sign. I set the subform visible = false and after printing visible = true. I don't see the STOP-sign, only a white background. When i set execution step by step then everything works fine.
What i'm doing wrong?

Try adding a "DOEVENTS" in the routine that handles these actions.
This command tells your system to keep doing other things.

A Me.Repaint would be better.

Also, as an aside, I find time based interfaces to be problematic on a number of levels.  Always better to leave the user in control.

For example, give  them a command button to indicate they are done, rather then having to wait 15 seconds.

Jim,

You are right.  But the boss has always the last word.
