Never mind, I understand my problem!
At first I thought it was because the module is in cache but I restarted Pythonista and the problème was still there. However, it gave me a hint: how about the cache. That is when I realized the I am loading that very same module within pythonista_startup, which happens before I use my current directory.
Problem solved! Probably the fastest resolution on the forum... my bad! LOL!! :o))
