[CLOSED]IE8 : Slow first calling of Ext.Msg.alert

[vladsch]

Hi,

I have strange behaviour on my local machine. First calling of 'Ext.Msg.alert' under IE8 is very slow (few seconds)

Ext.Msg.alert("title", "msg");

I tried the same code from IE8 console on online sencha examples and alert works very quickly but locally first calling too slow
Here is profiler result from IE8 (if it is useful for you)
IE8_Profiler.zip

P.S. Creating new window works quick for me

Is this in any particular mode?

Because the msg-box example works OK for me. And when I execute your fragment in the debugger it displays quickly.

Hi,

I found the issue. I run the sample under Visual Studio with debug mode (IE8 was in debug mode)
If run without debug mode then alert works quickly. Very interesting, ExtJS 3 alert under debug mode has no such issue

Thanks for the help
