was doing things like layer editing, cut selection

with spring (game client)

C:\Windows\syswow64\kernel32.dll(BaseThreadInitThunk+0x12) [0x76683677]
[f=0047744] (31) C:\Windows\SysWOW64\ntdll.dll(RtlInitializeExceptionChain+0x63) [0x773D9D42]
[f=0047744] (32) C:\Windows\SysWOW64\ntdll.dll(RtlInitializeExceptionChain+0x36) [0x773D9D15]


Would changes to environment variables cause something like this, since i had to change them about a week or so ago? Due to hard drive partition.

Would ccleaner do this?
