Hello,
I received the file you sent and completed the package installation. Thank you for your help.
However, the program crashes while editing the Columns title using the Editor. I tested it using Lazarus 4.0, I'll test it a bit more and ask again if it's still a problem.

I tried to download and install TeeGrid-Registered-1.18.exe.
But I get an error that "vkSpace" cannot be found.
Please tell me how to fix it.
I'm using Lazarus 4.0

Thank you for your kindness.
