Director converting symbol's case from lower to upper

Question

put symbol("bd") -- BD
any thoughts as to why this would happen?
it only happens every now and then, even though I am running the same .dir file;
furthermore it is not converting every lowercase string to uppercase;

Answer 1

well, this is simply an illustrative example of what is occurring;
what is actually occurring is:
my_prop_A = my_list_A.getPropAt( i )
my_value  = my_list_B[ my_prop_A ] --- error occurrs here
my_list_A is created at runtime from an external text file with ONLY lowercase letters;
my_list_A looks like: [#a : "something" , #aa : "something" , #ab : "something" , ... , #bd : "something" , ... ]
at this point I obviousely wondered if there was in fact an #BD within my_list_A ... maybe some type of anomoly conversion; however, there is nothing;
so if I:
put symbol("aa") -- #aa
put symbol("bd") -- #BD
once this happens it throws an error because there is no my_list_B[ #BD ] ( though there is a #bd );
in order to fix it I do all kinds of stuff, and there is no consistency to achieving the solution; on any given day this might work:
    --    close the 3dpi
    --    delete w3d and text files which have data that is used to build my_list_A
    --    recompile scripts
    --    save and compact
    --    close director
    --    restart my computer
    --    open director
    --    re-import w3d and text files which have data that is used to build my_list_A
but then on any other day that same set of steps might not work; some times I go through this same process 4 or five times, and then all of the sudden it works;
etc. with other solution approaches;
