ActiveX Sprayer: A Real World Adventure with Enterprise Mode for Internet Explorer

Before we released Enterprise Mode for Internet Explorer 11, we ran a fairly large pilot program – we targeted 30 customers, and ended up with more than 90. But there’s still always the question – will we have, by chance alone, gotten unlucky and chosen a group of very non-representative customers? So far, however, what…

Troubleshooting and Fixing Session Cookie Problems in IE11

Another browser, another version check crisis… So, like many of my esteemed nerdly readers, I pushed “go” on upgrading to the Windows 8.1 preview the first opportunity that I had. And, naturally, the first thing I started doing was finding the broken stuff. Unfortunately, it didn’t take me long. We have an internal conference twice…

Update on the Weight Watchers Mobile Site on IE10

Back in December, I blogged about the failure of Weight Watchers Mobile on IE10, which affects peoples’ fancy new Windows Phone 8 devices, not to mention their Windows RT devices like the Surface RT.

Debugging the new WeightWatchers Mobile Site on IE10 for Windows Phone 8

It’s been a while since I’ve done a debugging post, and I thought it was about time I came back and did one again. As some of you may have figured out, I travel now and then. (I am at just over 195,000 BIS – butt in seat – miles so far in 2012.) And,…

There is no substitute for practice. And, it turns out that the sort of folks who really excel at app compat can…

Debugging a CSS Issue with IE9: Mötley Crüe Edition

If you want to master app compat debugging, then I really only know of one approach: practice. Find things that are broken, and then find out why. If you have to look too far for something broken, then you must be significantly luckier than I am! Now, I prefer to listen to Mötley Crüe when…

Debugging the Missing .NET Tab for Managed Applications in Process Explorer for Windows 7 x64

I was reading through some documentation on Sysinternals Process Explorer the other day, and one bit that caught my attention was some detail on the .NET tab. So, I pulled up my trusty managed StockViewer application, and went to go and look at that tab. Only… …it wasn’t there. Fascinating. So I found another managed…

The Case of the SUA Missing Log File

Since I’m using Mark’s tools, I figure I may as well steal his blog title scheme… I had a customer come to me with a question on Standard User Analyzer (SUA), looking for an explanation for why it was coming back with the following error: Failed to load log file C:\Users\…\AppData\Local\Temp\sua No (valid) log file…
