Hey guys I've noticed recently some odd behavior regarding google chrome and my download stacks in the dock. I have my download stacks folder set so that the most current downloaded object shows up as a preview (ex. if its a pdf a photo of the pdf appears). However recently I've noticed that when i download some .rar files or mp3's, the preview in the stacks icon is just a blank text document. its not until i click the stack and it fans out that i see that a preview of my downloaded file (ex. mp3 will show its album art). when i click the stack again and the items fan back into the stack, the preview once again turns back into a blank document image instead of the corresponding mp3 image. i've never encountered a problem with this with safari. Has anyone ever encountered this error before? thanks.
