Gmail / Chrome on iOS: JavaScript issue

I just got a report about an issue with Gmail's built-in Chrome browser and our software. When the issue occurs, some of the buttons in the software stop working (no response).
For example:
  • The sign up button on the registration form
  • The Save Profile button in the User Control Panel


It was caused by an incompatibility between ASP.NET 4.0 and the Chrome browser on iOS. When the problem occurs, using the "Open in Safari" button doesn't help, either. The problem propagates to Safari this way.
However, Safari itself when used to view the forum directly (without using "Open In Safari" from Gmail) appears to be working without any issue.
The issue was talked about on StackOverflow.


The only solution that works appears to be upgrading from ASP.NET 4.0 to ASP.NET 4.5. ASP.NET 4.5 is an in-place upgrade and highly compatible with ASP.NET 4.0.
Our software works with both ASP.NET 4.0 and 4.5. But due to this weird, undocumented issue, I highly recommend everyone using our software to upgrade to ASP.NET 4.5.
Many people are using the GMail app on their iPad / iPhone, and this can be a potentially show-stopper for them.
ASP.NET 4.5 doesn't work on Win 2003.

Special thanks to

for reporting the issue after testing our mobile web app in Gmail + ASP.NET 4.0.

thanks for the heads up! I got a few users who ran into exactly the same problem but I couldn't figure out why. One of my sites is on 4.0 (win 2003) and the rest on 4.5... never thought ASP.NET runtime could mess things up like this.
I've been thinking about migrating away from 2003 for a long time, and this is the last straw.
