What Can Prevent a Window From Updating?

[Jerry Daniels]

Rob,

I used to use "go to this card" to force updates in HyperCard. I would call
it right after the result of the dialog was obtained. I haven't tested this
with Revolution at this time.

You might try that.

Subject: What Can Prevent a Window From Updating?

Hi All,

I have a problem where the stack window refuses to update even when 
lockScreen is false.

I have a handler that displays two ask dialogs, creates a new card 
including info from the dialogs, and opens an empty field for input. 
This basic logic has been working for some time, but recently, 
although Rev says (via the message box) it is on the new card and I 
can see the cursor positioned where the field should be, the window 
image has not changed except that the portion that was under the ask 
dialogs is white.  I can use the menubar to go to any card.  I can 
ask via the message box where I am, and I am told I am at the right 
card; but the image in the stack window NEVER changes.

If I run the handler starting from a card that is the same format as 
the new card, I can click on a button that is supposed to lock/unlock 
the input field and change it's own icon & toolTip in the process. 
When I click on the button, the field locks/unlocks and the toolTip 
changes (although the screen space beneath it does not refresh when 
the toolTip disappears) but the icon, though changed in the button's 
properties, does NOT change on the screen.

In a nutshell, it looks as though the screen is locked, but the 
message box says lockScreen is false, and I can find no other global 
properties that might control this behavior...which occurs in both 
1.1.1 & 1.5A7.

Does anyone have any suggestions as to where to look for this bug?

TIA,
