I had an interesting problem occur and I think found the source of the problem but I don't understand it.

In the main display of a record I fill the screen with 3 windows showing various bits of data. Windows 1 and 2 the display was normal. Window 3 was blank.

After several tests I was convinced the data was there but just invisible so I guessed and wrote 'set console on' at the start of the program that runs this window and behold the data appeared. A reindex command immediately before had the same curative result.
.
Nothing actually turns the console off before this happens so I have investigated the first modular program on the list of programs that run in that window. As it happens that whole program was 'highlighted' - as in SELECT ALL when you go to move or copy a portion of text.

So I de-selected the text and removed the set console on and all is working again.

My question, could the select all have had an effect on the display - in other words could VFP go through the program without displaying the results on screen because it was highlighted.


thanks
