SSL VPN - RDP Time outs

[#1]

I am using a fortigate 200A with V3 MR7 the latest firmware. We have setup SSL VPN in web mode. Most users use SSL VPN to setup bookmarks for RDP to their desktops at work. But I get many complaints that their RDP session disconnects and they have to connect again, or sometimes they cannot reconnect. They are mainly java errors. Some java errors they get is: RDP error java.lang.ArrayIndexOutOfBoundsException Coordinate out of bounds! [OK] It happens out of the blue not when they are doing a specific thing. We are using the latest firmware. Anyone having this experience. ANy solutions for this.

Does anybody know if there is an undocumented CLI config entry that can set the web client to auto-reconnect if in tunnel mode? The software client seems to reconnect without issue. Thanks in advance
