In previous versions, when I hit a break point in my web application the task bar icon would flash to notify me.
Now, the icon is flashing all the time - I think perhaps to indicate resources have updated.
I don't think that this is necessary and actually is detrimental.
Normally an icon flashes when you need to attend to the application (e.g. if you have hit a breakpoint and need to step through the code!).
Flashing the icon to say that resources have been deployed is distracting and meaningless.
Each time it flashes I switch back to IDEA thinking I have hit a breakpoint or that there is something to attend to but it is nothing!
