Hi, I have a custom module that is really simple, a textbox and a button that user enter a post code into and the button in code collects the postcode and sends as a parameter to an external mapping webpage.

The strange thing is that every now and again the text box becomes smaller on screen and the button does not fire.. If I recycle the app pool it clears and works.  Any clues anyone?..

Sorry for delay in posting but I have not been able to access the forum for some reason??.  

Anyway, I did find a viewport rule with a minimum and maximum scale<dnn:Meta runat="server" Name="viewport" Content="width=device-width, minimum-scale=1.0, maximum-scale=2.0" /> I have altered this to a more normal initial-scale=1.0 so will see if this helps.
