I have a simple run-time database. From the main menu, user's click a button with an openform macro to open a form in datasheet view. This form has a custom built shortcut menu with sorting and filtering options on it which works well. The problem is, the form will work for several days with multiple users using the form simultaneously, then it freezes. When it freezes, you can click the button on the main menu to open it, but nothing happens. After this happens, if I open the database in accdb mode and double-click the form in the navigation pane, it won't open, it does nothing. However, if I open it in design view, then click View in the upper left hand corner, it opens in datasheet view just fine. But back to double-clicking it in the navigation pane and it still won't open. This goes on for a while, then suddenly it works again and I have no idea why it suddenly works. I am not a programmer so this is a simple form built in graphic mode. I have tried compacting and repairing the database, and it changes nothing. I have tried rebuilding the form from scratch and the same thing happens. I thought perhaps it had something to do with the filteronload or orderbyonload and have turned those options off. Any clue what's going on? I have built these simple forms 100 times and never had this problem before. I would appreciate any help I can get. I have searched google for hours with no results.
