Jump Desktop 4.0.3 (released July 21st 2011)

• Right clicks do not work properly on Mac Snow Leopard 10.6.8
• OS X Lion Compatibility Notes
• 23/07/2011 6:18 AM: Update: App Store issues seemed to have resolved themselves. 4.0.3 is available on the App Store.
• 22/07/2011 9:17 am: Even though the 4.0.3 update was released about 18 hours ago, it has still hasn't showed up on the App Store. We're following up with Apple Support right now. In the meantime if you urgently need to update here is something you can try: Delete Jump from your device and redownload it from the App Store. Even though the App Store displays version 4.0.2 as the latest version, you may end up downloading the updated 4.0.3 (this worked for us two out of three times). You can check if you have 4.0.3 by tapping the settings icon on the top left hand corner of the main Jump screen and then tapping the About row. Warning: Deleting Jump from your device will also remove your Jump settings. You will need to reconfigure Jump after the download.

• 20/07/2011 11:04 AM: OS X Lion users: There is a known issue when logging into OS X Lion. We are currently testing a fix for this issue and will submit it before the end of day today.

• 29/04/2011 2:08pm PDT: We've finished investigating login problems with 4.0 and have identified a fix. Jump 4.0's NLA implementation does not work properly with domain-joined computers. We've fixed this issue in 4.0.1 and re-submitted the app to Apple at approximately 11:15am PDT. In the mean time, a work around for this is available: Tap the blue arrow next to your server's name in Jump and edit the connection settings. Scroll down and turn off the NLA mode option and try reconnecting.
• 28/04/2011 11:20pm PDT: Users have reported screen corruption and a Jump Desktop crash when the server end is restricted to 15bit color mode (this is an unusual scenario). We've fixed this issue and submitted the fix in the 4.0.1 update to Apple.

• 27/04/2011 9:50PM PDT: Users on iPod 2G and iPhone 3G have reported crashes when connecting to RDP servers. Preliminary investigation reveals that this might be due to a out-of-memory issue on older devices with less on-board RAM. A work around for this is available: Tap the blue arrow next to your server's name and edit the connection properties. Tap the Quality row and turn OFF Bitmap Caching. Save your settings and try connecting again. If you're hitting this problem, we'd really appreciate it if you could please report it to: support@jumpdesktop.com and help us test the fix.
