I tested on Windows 7 32bit, Firefox 3.6 and IE 8.
I disabled eAccelarator, but did not touch APC:
[apc]
apc.shm_segments = 1
apc.shm_size = 128M
apc.ttl = 7200
apc.user_ttl = 7200
apc.num_files_hint = 1024
apc.enable_cli = 1
[eAccelerator]
eaccelerator.shm_size = "0"
eaccelerator.cache_dir = "D:\xampp\tmp"
eaccelerator.enable = "0"
eaccelerator.debug = 0
eaccelerator.check_mtime = "1"
eaccelerator.filter = ""
eaccelerator.shm_max = "0"
eaccelerator.shm_ttl = "0"
eaccelerator.shm_prune_period = "0"
eaccelerator.shm_only = "0"
And yes, there is an error log:
