CC doesn't clean Comcast temp files?

First of all, thanks for a fantastic cleaning tool, it's been working splendidly for me for a couple of years now.

However, I have encountered my first problem. Last week I switched from Verizon DSL to Comcast. With Verizon, CC used to clean out everything including whatever I entered into the search bar. Now with Comcast it does not. I have to manually delete entries. I would like it to happen automatically when I run CC as it used to.

Any help appreciated.

Did you change browsers as well as ISP ?

Other wise it shouldn't make a difference.
