Error in input field

Hello All, We have a problem with error in field of an input array. We use HP9000/800 with HP-UX 9.04 Informix Compiled 4GL 4.13.UD1 with Online 5.04 UC2 It seems to occur when in an input array someone does a look up in one of the fields that pops up a display array or an input array to search or input new data. When they return from the popup window and try to move out of the field we get 'Error in field'. I have looked at the data in the row and its OK and the only way to fix it is to redisplay the row to the screen row, then every thing is find. Another thing is odd when returning from the popup screen if you call arr_count it returns the number of rows in the popup window not the current number rows in the array. Questions. 1) Has anybody ever seen this before? 2) What did you do about it? 3) I dont think it causes any harm and there are work arounds but does anybody really know? Carl Wilson carl@midrex.com
