Hullo. Thanks for the awesome add-on Just getting back into WoW after a hiatus and found this problem. Not sure if it's been reported already.

Problem: Experiencing very slight lag or graphics/movement stutter when casting spells, mounting, etc.

Testing: I had all other add-ons disabled except for Jamba and Jamba-Toon and the problem appears. When I disable Jamba-Toon but leave Jamba as the only add-on running, the stutter goes away.

My specs: HP Pavilion dv7-4029TX, CPU: Intel Core i7-720QM Processor, Video card: ATI Mobility Radeon HD 5650 1GB, RAM: 8GB DDR3, OS: Windows 7 Ultimate 64-bit, all settings at default with no other programs installed except for Firefox 4 and nothing else running except for Innerspace/ISBoxer. Connected via Gigabit LAN using CAT6 to a TP-Link TL-WR1043ND Wireless N Gigabit Router, which is then connected to a D-Link DSL-G604T (Firmware: [latest] V3.02b01T01.AU) on an ADSL connection with an average speed of 6Mbps down and 0.32Mbps up tested via speedtest.net. Average in-game ping of 500ms playing in Proudmoore-US from Australia. Also tested with the TP-Link router bypassed, connected using CAT5 as well as CAT5e to the D-Link modem/router.

If there's anything I missed out, please pm or reply to the thread.
