IE9 crash and reopen

Question

I have a Flex application that opens in a new window when I click the javascript link in another window. If I close the flex application window using the close button of the browser while it still loads, or rather, before the datagrid is displayed, the view of the screen freezes for less than a second, if I close the screen at this moment, IE9 and the following message appears:

A problem with this webpage caused Internet Explorer to close and reopen the tab

I tried all the solutions that I found on the Internet, but no one worked:

• adding website to compatibility mode
• using different versions of flash player
• java plugin update
• disable / enable plugins
• reset Internet Explorer settings
• install latest updates
• using microsoft "fix it" utility
• Use software rendering instead of GPU rendering.

Answer 1

I had a similar problem with Firefox and Chrome. This happens to me when I get a long list of data that needs to be processed before it is shown to the user, or if I use a graphically intensive component that causes the browser to freeze due to the processor load that is applied to it.

Try checking your Task Manager when this happens, and check if the browser uses your processor all the time, if so, then you need to work on making your code more efficient by reducing the preprocessing of the data and doing more when the user scrolls data or uses list-based components instead of repeater components, since the latter tend to make everything very slow, even if you use simple text visualization tools.
