on the IPS Marketplace main page, in the center section, in the first area, labeled 'What's New' - click on right arrow to slide right and do it again.

Now click on left arrow ... click click click click [nothing happens] ... damn elevator is broken again. Take the stairs?

It works for me just clicking the right arrow twice and then going back...

What doesn't work is if you click the 'grayed out' arrow and then try and click the darker arrow back.. Even forward does this.. Click the back arrow first, then try and go forward...

You should bug report it.

hmmm, thought about bug reporting but I have no idea where to report it ...

for me, I click the right arrow twice, just like you, and then move the cursor over to the left, dark arrow ... and no luck, the elevator is stuck.

I'd say that's a downloads thing...

I reported this bug last week. It's fixed for 2.5.3.

Yes, that issue was already reported and is fixed for the next release.

hmmm, thought about bug reporting but I have no idea where to report it ...

When finding a bug, report it under the app you notice the issue in. If you think it's something specific to the IPS site/community, then report it in 'IPS Web Site and Client Area' or 'Documentation' area, which ever is more appropriate.

Just some guidance for the future. :)
