Question
Snort 2.4.3 logging options
I just upgraded snort to 2.4.3 and this seems to have broken ascii logging.
The command line:
C:\Snort\bin\snort.exe -c "C:\Snort\etc\snort.conf" -K ascii -l "E:\snort" -i 2 -h 10.0.10.0/24 -U -y -z -d not host 10.0.10.254
creates the alert.ids file but no rule hits
logging to console sees the traffic coming in, but no alert logs

Your right, have you tried switching the order.... -l "e:\snort" -K ascii it may make a difference I'm not sure. Failing that you'd want to review the rules that are set to alert or perhaps any thresholding you may have set in your snoft.conf files
If your using snot or stick to trigger alerts the -z may be preventing the packets from being issued as an alert... Try using nmap (if you have port scanning rules enabled to alert) of GFI's Network Security Scanner to trigger alerts
The -z switch tells Snort to only allow alerts to be generated for packets that are part of a known, established session. This allows Snort to greatly reduce the effect of anti-NIDS tools like stick and snot.
I've never used a single number for my snort interfaces on a win32 box I'll have to try that "-i 2" nice and simple.

Does your snort.conf file have the logging dir specified in it? otherwise you might want to add "-l" (dash el) and specify a directory to log too. Also in the past if your log's were around 2gig's then they needed to be deleted or archived and then erased... something to check I guess.
