I have a custom control code snippet which causes a data type mismatch error when it runs.

The offending function is 'used(.cDisplayTable)', .cDisplayTable being a control property. When I look at the value of the property after the error it contains the correct value of the correct type.

When I insert a 'assert .f. message ' before it and step thru the offending line with the debugger it runs OK - no error.

This is driving me nuts.

Oh - yea - this is a piece of code that has run sucessfully for years.
