Designer froze and stopped working

Question

While editing column names in Write CSV File, the mouse cursor went into the read state and Designer froze and stopped working.
Can you tell me the cause of this behavior and any workaround?

Answer

If the resources such as CPU and memory of the client PC on which Designer is running are exhausted, Designer may become slow or freeze and stop working.

During certain process such as editing column names in database components, Designer performs relatively heavy load process such as I/O process and communication process.
Therefore, if you are performing a heavy load process in the background during Designer processing, you may be able to improve Designer's performance by interrupting the background process.

Also, please consider increasing the CPU or memory of the client PC to improve Designer's performance.
