Clicks on a lock text field send mouseup/down events to the field script. If the script itself clicks on the field, then it will send the event to itself, causing infinite recursion. There are several fixes. The easiest is to surround the click actions with setting and clearing the locktext property. You may find this slow. You may also just calculate the line number and select it: select line i of field x. Then you don't have to click. Note that you may have problems with lines which wrap. Finally, the easiest thing to do (if you don't need the line number, but just the line contents) is not calculate anything but just: set locktext of field x to false click at the clickloc select the selectedline put the selected into into linevar set locktext of field x to true This lets hypercard do all the calculation -- baum@apple.com (408)974-3385 {decwrl,hplabs}!amdahl!apple!baum
