Nah, anything you do with computers will only bring you back to the same old interface problem...you.
I recognize what you are saying & have played with CMP all night.
This is a tough act to explain as I have also met with assets that would formerly work ok but the next day...
Starting from the beginning of Auran Trainz we have had a pretty tough bunch that knows what they are doing, however we have had several major updates & releases to the game that have improved performance in a subtle way...some not so subtle.
The transition from TRS2004 to TRS2006 gave a learning curve as we call it. What was acceptable to '04 became legacy to '06.
I can think of several reasons why the chosen asset suddenly don't behave right, but as far as it goes, it was broken...the fix has been previously reported.
I used a demo for six months before I bought into the Auran Trainz program, so I had practice dealing with the program.
You cannot learn this over one night.
You must decide basically this...why do you wish to own a train-sim?
If it has anything to do with what you found in the beginning, continue on thus...you will learn by practice.
At 51 years, I have noticed that many young people are surprised by my knowledge of computers...I myself am surprised at the number of young people that are computer illiterate, can't spell, can't use punctuation, want to cuss, can't form sentences, use a stone-age creation called "firefox" that bunches all text into one ridiculus paragraph, can't even make a screenshot in-game(they have bu-cu pics in a folder they can't find) let alone post it on the web & generally post only to flame regular users...etc.
I need you to post the kuid number(it has a < and a > at each end. KUID means "kool-things user-id) like kuid:127571:8488 for this car your angst is about.
I have everything, so I probably spent a few minutes screaming at this one...(I don't do that, just kidding).
My whole deal past fixing this appliance is to illustrate how easy it is to take a covered hopper that carries 80,000kg of woodchips(never carried in a covered hopper...trust me) to a 100,000kg capacity car that either will carry foodstuffs or stuff that would kill you...or make your life better.
Let us help with this & any other project you need to know.
The Auran Trainz Community is the most friendly of any bunch, as far as train-simulation gets.
