Overflow Error

[User (Legacy)]

Using a 4 pane chart if I open my form with a pane not visable and then try 

to make it visable I get the overflow error below.  If I first open the 

chart with the same pane visable I can go back and forth without error.

System.OverflowException was unhandled

  Message="Overflow error."

1.  First  I show a 4 pane chart form making frames visable based on last 

state stored in a database.  (Works fine for all initial states)

2. Then using a new command created on the toolbar a form is shown that 

allows the user to hide or unhide any of the 4 panes.  (This works fine for 

any pane that was initially shown on the first form as visable.  If the pane 

was not visible (hidden) when first shown the overflow error occurs when the 

user tries to unhide it.)

All steps in the Hide/Unhide Button Click Sub execute.  The error is thrown 

when the Sub closes.  I assume that´s when the redraw starts.

I found a work around for the error as follows:

I initialize the chart with all panes visible in the  forms Load event and 

then hide panes as required in the forms Activated event.  This works fine 

leading me to believe the problem may be one of timing in the re-draw.
