iTunes "Check for Updates" button no longer working for Apps
In the Apps library the Check for Updates button is no longer working. Clicking on it will either bring up no response or the top of the screen will quickly flash "Accessing iTunes Store". I know that there are updates because I am still seeing them on my iphone. This has been going on for two days now, before then I have not had any problems. Any help would be appreciated.
iMac, Mac OS X (10.6.7)
