I think there is a problem with the thread How to enlarge textbox control when it is moused-over?
First, note that there is a table in the upper-left. The table has three columns and two rows. I think that is not normal. The table is easily overlooked (not seen) but I think it is not normal.
The table is not a problem; it might be a symptom. The problem is that when I click the Reply button, nothing happens except "Loading..." appears in the upper-right. I cannot reply to the thread. Perhaps the problem is that Rakesh posted some sample code and (perhaps) that sample code is causing a problem.

but instead of displaying code it render on thread page and display at top of the page section.

If (X>=0 and X<=200) And (Y>=0 and Y<=400) then
DoCmd.RunCommand acCmdZoomBox
End If
Change the X and Y values as needed for the size of your control.
This would be very very annoying for any user (well, for me anyway!).
Why not code the control's Double-click event:
DoCmd.RunCommand acCmdZoomBox
This way the control 'enlarges' only when the user wants it to, not
just when they inadvertently pass the cursor over it.
