(TCC 15.01.52 x64 Windows 7 Build 7601 Service Pack 1) I've been away from TCC for some time. It seems I've forgotten some things...The online help notes: popup windows can be moved/resized, and remember their sizes and positions. But the history and dirhistory windows sometimes resize themselves (always smaller than expected), with dirhistory sometimes shrinking to a single line. I have to keep resizing them manually -- especially dirhistory. I'd like to have at least 30 lines displayed. Can I set a default? I'm having trouble invoking Perl (using 32-bit ActiveState Perl 5.16) scripts this way at the command line: scriptname.pl Result: Error (SYS): Invalid class string. Doesn't happen under cmd.exe. With the Perl support disabled via OPTION, the error message might appear, but I can't tell because a new TCC window opens and then closes too quickly to see what's in it. If scripts are launched like this: perl.exe scriptname.pl — no problem. I have a .PL variable set as follows: .pl=c:\perl\bin\perl.exe. Assoc shows a definition for ".PL" ("perl.exe"). Prepending "perl.exe" would be ok for running Perl scripts via .btm files. But I'd like to avoid having to prepend "perl.exe" each time at the command line. What might I have set incorrectly? I know I noted this in a message quite a while ago. Wondering if anyone's had the same problem — and solved it. (Do I need to uninstall the x64 version of TCC and install the 32-bit version?) Thanks in advance.
