I installed the TomatoCart appliance using VirtualBox (on Win7 64-bit). 

I was able to open the default store in both IE (10) and Chrome using either the static IP or the hostname after adding to Win7's \Windows\System32\drivers\etc\hosts. And both browsers seem to display the demo store fine including animations.

When I try to access the admin page -- either via "IP-address/admin" or "domain.tld/admin" -- I am unable to login using IE 10. When I type in the admin username and password and click the Login button, the Username and Password text boxes are cleared and the Username text box gets focus. If I type in an invalid ID or password, a message box is displayed saying "Username and password do not match."

Chrome, on the other hand, accepted the login ID and password and then displayed Admin "desktop" controls briefly but the browser window goes black.

I posted to the Tomato Cart general support forum and someone posted a reply suggesting unchecking Chrome's System | Hardware acceleration Setting. Doing so did indeed resolve the issue.

Firefox seems to handle login and admin panel display without issues.

It is at least encouraging that there were 2 replies to my post in less than a 24-hour period.
