>>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.

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