Also, I notice that bitcoin-QT is experimental software. Is there an application out here that is not experimental? With millions of dollars being exchanged there has to be a solid, fool proof application out there. What is it? How do people normally do bitcoin transactions?
Bitcoin itself is experimental and risky. So no there is no uber stable bitcoin wallet software.
But the problems you are facing are definitely extraordinary. I suspect there is a problem with your PC's hardware. Bitcoin-QT puts a lot of stress on your PC when it is downloading the blockchain. The hard disk, CPU and maybe RAM is stressed the most. If your hardware is not up to scratch it can fail under the stress. I suggest you do a scan for bad sectors on your hard drive. Repeated corruption of the database suggests a failing hard drive.
The guy clearly doesn't need qt. He said "How do people normally do bitcoin transactions?"
He just wants to do normal transactions, and you point out yourself so vividly all the stresses qt places on a typical system.
Have you ever tried electrum? It places no strain on your system, and is running in 2 minutes ..... and yes, its stable as well.
We want to get normal people using bitcoin and keep recommending they use qt. What gives?
