Yes, like you I find some of the buttons here today and gone tomorrow, makes it hard to learn the board. I have found several things one day and wanted to go back and use them again the next and never could find them. Not sure why that is happening. Whether the developers programmed the board themselves or used a package (as programmers call it) there are some problems with it (as there always is when you put something new into the system to be used) Ask me how I know ha ha! I don't care how much testing one does, once it goes into productions the little bugs multiply and come out of the woodwork like crazy. I have always said one should get a group of people to beta test a system before it is put into production. The users can find ten time more mistakes than the programmers can. But supervisors and managers don't always agree with that philosopy and if it is a package the seller promotes his package with a "ready to go" sale and it's not ready to go when the buyer puts it in as everyone has different ideas and needs and the seller can't think of all of them that's for sure. My two cents worth for today.
