问题
I'm using Uploadify to allow for multi file uploading in my web application. It has always worked across IE 7,8, 9, FF 3.6, Safari and Chrome.
Today I discovered by accident that it was working in each browser yet not in Chrome. I'm currently on Chrome 10.0.648.82 beta. The issue there is that I can select files to upload, yet after that nothing happens. I put alerts in all Uploadify events and non get fired. Then I went to the official demo site:
http://www.uploadify.com/demos/
...and discovered that it does not work for Chrome there anymore either. I am running Chrome as default as can be, so it updated to this version itself. I have all default settings intact and no popup-blockers, ad blockers or any other add-in installed. I tried to debug using HTTP Fiddler, only to conclude no HTTP request is made at all after selecting files to upload.
Does anybody knows what is going on? Is this a Chrome issue or Flash issue? Are there any known resolutions?
PS: I am on Windows 7 64-bit.

I agree, I think it is a Chrome or Flash issue (since Google ship Flash inside Chrome).
The uploadify demo page is working for me in Chrome 12.0.725.0 (which is the current dev release). You could try switching to the dev or beta channel to see if the issue is fixed for you.
Also, I found this other question that could help - Uploadify IO error #2038 random on Google Chrome

Since it just broke with the new Chrome beta, I am 99% sure it's a Chrome issue. It works for me in v9 of Chrome. I see you have posted in the support forum of the plugin, so let's see what the developers have to say on the issue.

Double check Servlet,that is called by Uploadify and Filter classes if they exist.
Possibly it a matter of cookies handling,that are handled specifically by Chrome plus by Flash.
Flash doesn't set cookies(jsessionid).
Check this:cookies in Flash
And this(my problem with Uploadify,especially last comments to answer):
Uploadify plugin doesn't call Java Servlet
