sample02_controls and sample03_image crashes.

[Yuriy Balyuk]

these two samples are crashing with no message in console:

• sample02_controls
• sample03_image

os: windows11
nim: latest

i see that they can't load cat image.
tried to fix with the following patch, but only sample02 works fully after that. sample03 loads cat image ok, but also freezes the app completely.

i think this issue is related: #323

but strange that i have no traceback on my system.
