I've released version 0.1.1 of SlushMiner on SourceForge (https://sourceforge.net/projects/slushminer) with the following improvements:

• Miners automatically retry after errors (like lost connection) instead of sitting all night without running. A new dialog window will appear when a miner has a failure, and the miner will retry after 1 minute. If it fails again, this increases to 2, then 3, then 5, then 10. If it succeeds, it disappears from the list, and if the list is empty, the dialog closes itself (this way you don't wake up to an error message when the pool server has a hiccup in the middle of the night, but is running fine in the morning). If the miner fails to start right when you click START MINING, however, the standard error message will appear like before.
• Handles JSON errors correctly (so the program won't crash when the currency market data is corrupt)
• Errors sent by POCLBM to StdErr are now logged correctly (this should help with diagnosing problems)
• System tray icon context menu (so you can right-click on the tray icon when minimized to start/stop mining)

Let me know what you think!
