This works in every browser I tested except IE8 (timeout/interval issue)

[Lucy]

This (part of a function) does not work in IE8:

	fTiming = setTimeout(	function()	{		fTiming = setInterval(		function()	{			fadeEffect(tLayer);		}, step); 	},fadeTime);

'fadeEffect' does work, and it works if I use setTimeout with it, but the above code literally does nothing, and I don't even get any error messages. It works in Firefox, Opera and Chrome. Does anyone know why?

IE might have some problem using the same interval again.

[Lucy]

Hm.. it doesn't even run once, though? Also, I'm clearing the interval each time this function runs.

Turns out it has a problem with using a variable as the number of milliseconds.

If opacity: is used older versions of IE used a different method of applying transparency with filter: alpha(opacity=x); but with IE9 it finally (5 years+ later) followed the method used by other better browsers.

Yeah, I spent ages figuring that one out, lol. This still isn't quite fixed, as it turns out - but now the IE developer tools window has gone and won't come back so I can't use console.log statements to figure out what's going on. Fun.

That's not a problem, maybe the variable wasn't set when that code ran. If you're still having problems you should probably post more code. The code you posted above should be fine in general.

You're right - I think the problem was actually that the variable was (accidently) a negative number.
