SYMPTOMS
When a form is run with a DO FORM command, it appear to enter an infinite loop, and you cannot release it. When the same form is modified with a MODIFY FORM command, a Syntax Error is displayed. It is not possible to open the form.



CAUSE
The value of a custom property has been incorrectly set to ; that is, the value starts and ends with a parenthesis.



WORKAROUND
You can manually open the form (SCX table) by using a USE command. Browse the SCX table, and edit the Properties memo field to remove the property that is causing the error. Then close the SCX table, and compile the form by using the COMPILE FORM command. Once the cause of the error has been removed, you can edit the form with a MODIFY FORM command.

NOTE: manually editing the SCX table should be performed as a last resort. Use extreme caution when deleting data from the SCX table.

If you must set a default value of for the property, place quotation marks around the the expression in the property sheet.
