### Describe the problem
In addition to opening them via the Arduino IDE GUI,… sketches can be opened directly either via file association or by passing their path to the IDE command line invocation.
🐛 This only works once per IDE session. After that, attempting to open additional sketches in this manner has no effect.
### To reproduce
1. Select **File > Quit** from the Arduino IDE menus if it is running.
1. Open a sketch via file association or command line argument:
```text
& ".\Arduino IDE" "C:\Users\per\Documents\Arduino\Foo"
```
🙂 The IDE starts up with the specified sketch open, as expected.
1. Open a different sketch via file association or command line argument:
```text
& ".\Arduino IDE" "C:\Users\per\Documents\Arduino\Bar"
```
🐛 The command exits immediately with no effect. The specified sketch is not opened in an IDE window.
### Expected behavior
Additional sketches can be opened via file association or command line argument when the IDE is already running.
