I’ve recently upgraded from Prof-UI 2.61 to 2.62 and I am now having link problems. It looks like the linker is finding a 2.61 version of the library but I’ve deleted all .lib and .obj files and built everything again from scratch.

We are building a Unicode debug build with VS 2005. I have included the output from the linker below

Any ideas on what might be going wrong?

Sorted! Turned out to be inconsistent use of the "Treat wchar_t as inbuilt type" option. I don’t understand how it was building with 2.61 now...
