I don't know if this has been already reported in other modules discussions, anyway I post this here, since I noticed this issue while using the Export stats to EnhSim config file function.
This is the Rawr data export:

As you can see in the first lines, weapon speed is incorrectly handled. Also in the tooltip for the weapons in the main Rawr window, the decimal character is a comma instead of a point.
This causes a DPS loss in EnhSim, if the weapon speed values are not manually corrected.
The problem may be caused by different Regional and Language Options in Windows, since I use Italian versions of the OS, but, interestingly enough, only the weapon speed is affected by this issue, while other stats are correctly showed.
I found this issue using Windows XP pro Italian and Windows Vista Home premium 32-bit Italian.
Versions of Rawr 2.2.5 and 2.2.6
