I'm using IE8, version of Telerik.Web.UI is 2010.2.836.35.
line 8464 character 1
In Chrome and Firefox I do not get this error.
Using IE debugger, I can see that error happens in next two lines:
Note, that function _fixIEHeight goes after
height was assigned. So, if height was negative (as in my case), Invalid argument error is thrown, and I have no possibility to check what this height mean because js is obfuscated.
If we have this _fixIEHeight call before
assigning the value, everything should be good, as function really fixes wrong values.
Now I can't give you easy scenario to reproduce, as RadEditor is highly tied with our application. Please reply if the information above makes any sense.
