I have long used the following Autotext definition (or rather the corresponding pre-1433 definition) for C++ with Visual Assist:
#w:
#pragma warning(disable:$end$)
#w:
#pragma warning(default:$end$)
Today I upgraded from build 1418 to 1433, and it stopped working properly.
If I type <#><w>, no Autotext shows up in Suggestions. However, if I rather type <#><w><backspace>, it does show up properly.
If I change the Autotext definition to _w instead of #w, it works as expected. I have confirmed that the problem exists in a new C++ project with an empty .cpp file.
