Copied data is settung DATE format in every cell????

[Turbo68]

I am really at a loss with this. I have a workbook that i have had for a while now and things were fine until recently. I have multiple tabs and i do have macros but i see no reason why this would be happening. What i have going on is I will copy lines of data from one sheet outside this book, using control C and control V, but when it put it in my tab sheet it changed every cell to DATE format!!! The format it is copying from is GENERAL and has text, numbers and dates. I used to be able to copy and paste with no problems but now it sets the pastes area to DATE format. I can use Paste Values but that takes my dates from the original and turns them into numbers.

Any help would be appreciated greatly as i am pulling my hair out trying to get this to work correctly again.

Thanks

Mike
