That's what I'd expect. in 0.90.0, I think all that was changed was the build code, so that the accelerator no longer builds be default.

No users of wxPython 2.8 will have this dll installed. anyone doing a clean install of MPL 0.90 should have _wxagg.pyd either. > At the bottom of the file backends_wxagg.py, there is an import > statement for _wxagg.pyd: > > try: > import _wxagg > except ImportError: > _wxagg = None > > Obviously this import always fails on wxPython 2.8, and is the cause of > the redundant error message. _wxagg.pyd is not needed with wxPython 2.8, > so the import should not be attempted at all. That was supposed to be checking whether _wxagg.pyd was there at all. If it's there with wxPython2.8, something odd happened -- maybe not that odd, it could happen if wxPython were upgraded after MPL was installed, but only if it's an old MPL or the accelerator build was turned on on purpose, overriding the default. I suspect you installed MPL 0.90 over an older version, which causes problems in various errors -- maybe the Windows binary installer could do some clean up first? So the key is this -- the accelerator is deprecated, so this shouldn't come up , and a couple versions down the road, we could probably remove the attempt to import it. > Instead, it should read like this: > > if getattr(wx, '__version__', '0.0')[0:3] < '2.8': > try: > import _wxagg # C++ accelerator with wxPython 2.6 > except ImportError: > _wxagg = None # default to pure Python > else: # wxPython 2.8, no accelerator needed > _wxagg = None That would probably work fine, but I'm not sure it's even worth it, unless anyone wants to run the accelerator with 2.6 and also have 2.8 installed, switching between them with wxversion -- a small pool of people! By the way, why not just: if wx.__version__[0:3] < '2.8' or even wx.__version__ < '2.8' which is think works fine. -Chris -- Christopher Barker, Ph.D. Oceanographer Emergency Response Division NOAA/NOS/OR&R (206) 526-6959 voice 7600 Sand Point Way NE (206) 526-6329 fax Seattle, WA 98115 (206) 526-6317 main reception [EMAIL PROTECTED] ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
